Making fun of people doesn't move the profession forward. It doesn't help your patients. It doesn't get that clinician who you don't agree with to change how they are treating. Social media can be a total echo chamber and create a very skewed sense of support and false perception of reach. (Aka, your followers already agree with you.) The folks who perhaps need to hear what you're saying tend to be insulated by algorithms, and what does manage to slip through, well, if it's a video of you making fun of their methodologies, one guess at how well that's going to be received.
I get it, it can be EXTREMELY frustrating to feel like you're fighting a constant battle trying to make up for all of the potentially less-than-correct things being said by seemingly misguided therapists…but making fun of how someone runs will never make them a better runner. If you want change, educate, don't imitate; educate, don't berate.
Your frustrations are valid, but at the end of the day, a parody post with no actual education is no better than a physical therapy session with no active interventions. As cliché as it may be to say, you must be the change you wish to see in the world. Social media is powerful. Use it wisely.
